During the Winter War, the Finnish
Air Force (FAF) obtained 30 Mk II fighters from the UK. Ten of the aircraft were
donated while the other 20 were bought by the FAF; all were delivered between 18
January and 16 February 1940.[17] The Finnish Gladiators served until 1945. The
Finnish Air Force obtained 45 aerial victories by 22 pilots with the aircraft
type during the Winter War and one victory during the Continuation War. Twelve
Gladiators were lost in combat during the Winter War and three during the
Continuation War.[17] Two pilots became aces with this aircraft: Oiva Tuominen
(6.5 victories with Gladiators) and Paavo Berg (five victories).

Besides the FAF Gladiators, the Swedish Voluntary Air Force, responsible for the
air defence of northern Finland during the later part of the war, was also
equipped with Gladiator fighters, designated as J8s (Mk Is) and J8As (Mk IIs) by
the Swedes. The Flying Regiment F 19 arrived in Finnish Lapland on 10 January
1940, and remained there until the end of the hostilities. It fielded 12
Gladiator Mk II fighters
